JAR-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 530,190, dated December 4, 1894.

Application filed September 10, 1.894- Serial No. 522,605. (No model.)

To all whom it may concern,.- A

Be it known that I, CHARLES E. LONG, a citizen of the UnitedStates, residing at Verona, in the county of Allegheny and State of Pennsylvani a, have invented a new and useful .Tar-y Closure; and I do hereby declare that the following is a full, clear, and exact description' of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to vessel closures.

The object of my improvements is to provide a jar or bottle or other vessel with an air tight closure by means of which such vessel may be sealed in a very simple and expeditious manner.

With this object in view my invention consists in the following construction and combination of parts, the details of which will tirst be described and the features of novelty set forth and claimed.

In the drawings: Figure l represents a central vertical section of a vessel having my improved stopper applied thereto. Fig. 2 is a top plan View ot' the stopper proper.

A represents any vessel, such as a jar, can or other like receptacle.

B is the mouth of the vessel provided with an irregularly shaped opening, the drawings showing the opening in the form of an ellipse or oval. The under side of this opening B is provided with a correspondingly-,shaped seat C.

D isthe closure or stopper proper, of elliptical shape, having a seat E along the top edge thereof, upon which is seated a ring or gasket F, which is interposed between the stopper and the seat on the jar.

G is a threaded stud which rises from the center of the stopper, projecting upwardly through the jar opening.

H is the clamping nut or disk, which may vbe of any suitable form and is screw-threaded to t the threaded stud on the stopper.

In operation the seat of the stopper is 'brought into contact with the seat on the jar and the threaded disk is screwed down against the top of the latter, which acts to bring a positive force to bear upon the stopper, thereby locking the same and hermetically sealing the jar.

The irregularly shaped form of the jar opening and the stopper, is essential or desirable in order that the stopper may not turn in its seat while being clamped and thereby prevent effective sealing of the joint.

It will be understood that other irregular shapes may be given the jaw opening and stopper. Other forms may be given to the screw disk which clamps the parts together.

No matter what the shape of the stopper and opening in the jar may be,it is desirable that the stopper may be easily removed and inserted in the vessel, and provision is made for that purpose.

This closure cork or stopper is very simple and is very cheap to manufacture and very eective in hermetically sealing all kinds ot fruits and vegetables.

I may provide the closure D with a secondary stopper I having likewise an elliptical valve and a threaded stud projecting upwardly through a central vertical opening in the stud G, and provided with a similar threaded disk L for the purpose of clamping the valve to its seat in the closure D. By this means I may convert a wide mouth jar into a bottle with asmall neck, or provide such a jar with means whereby tubing, siphons, &c., may have air-tight communication therewith. I may also provide the stud K with a vertical opening through which a clamp is inserted having a spider frame at its lower end bearing upon both valves D and I and held in position by a clamp on the tops of the studs.

I claime The combination in a vessel closure, comprising the vessel having an irregularlyshaped opening, a stopper of corresponding shape adapted to be seated upwardly, having a central opening therethrough a threaded stud upon the upper portion ofthe stopper, a screw disk or clamp adapted to be screwed upon said stud down upon the top of the vessel or opening, a second stopper having a threaded stud adapted to be seated upwardly in the opening in the first stopper, and `a screw disk for clamping same on the outer stopper stud.

CHARLES E. LONG.
